Used as bare overhead transmission conductor and as primary and secondary distribution conductor and messenger support. ACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity.

The galvanized single steel wires or stranded steel wires are suitable for cores of ACSR to improve its tensile strength. And they can also be used in the aerial transmission line as the line material of ground connection to avoid the lightning strike.

Stranded bare copper and copper alloy are suitable for overhead power transmission systems and overhead electric traction systems. 

This kind of spaced aerial cable ( SAC cable) is used for aerial power tranmission at 15/25/35 maximum system voltage. the phase to phase voltage is 10/20/33KV.
